This section provides information to help you troubleshoot general problems with your phone. For 
more information, see your system administrator.

tone or complete a call

 One or more of the following factors may apply: 

You must log into the Extension Mobility service.

You must enter a client matter code (CMC) or forced authorization 
code (FAC) after dialing a number.

Your phone has time-of-day restrictions that prevent you from using 
some features during certain hours of the day.

in the Application 
menu. 

Your system administrator may have disabled Settings on your phone.

The softkey that you 
want to use does not 
appear

One or more of the following factors may apply: 

You must press more to reveal additional softkeys.

You must change the line state (for example, go off-hook or have a 
connected call).

Your phone is not configured to support the feature associated with 
that softkey.

Cisco CallBack fails

The other party may have call forwarding enabled.

The phone shows an 
error message when 
you attempt to set up 
Call Forward All

Your phone may reject your attempt to set up Call Forward All directly on 
the phone if the target number that you enter would create a Call Forward 
All loop or would exceed the maximum number of links permitted in a Call 
Forward All chain (also known as a maximum hop count). Ask your system 
administrator for details.
